Answer:

<2 = 116 degrees

Step-by-step explanation:

alright so if angle 1 is 64 and you need to find angle 2 you gotta think about whats similar between them. They're both on the same line(railroad) and a straight line is 180 degrees. So now with this info all u gotta do is subtract 180-64 to get 116

  • [Right Triangles Only] SOHCAHTOA
  • [Right Triangles Only] sin∅ = opposite over hypotenuse

Step-by-step explanation:

<u>Step 1: Identify Variables</u>

Angle = 35°

Opposite Leg = <em>x</em>

Hypotenuse = 20

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute [sine]:                    sin35° = x/20
  2. Isolate <em>x</em>:                                 20sin35° = x
  3. Evaluate:                                 11.4715 = x
  4. Rewrite:                                  x = 11.4715
  5. Round:                                    x ≈ 11.5
